RELATED FIELD

A vehicle monitoring system and methods of use are provided. In someembodiments, a rear-view mirror and modular monitor system for enhancedviewing by a vehicle operator of areas within and/or exterior to avehicle, and methods of using the system, are provided. In someembodiments, the rear-view mirror and modular monitor system isconfigured for use on a bus, school bus and/or public transit vehicle.

BACKGROUND

Existing vehicle monitoring systems capture still images and/or videoimages, and display the images on a monitor for the vehicle operator toview. For example, many large vehicles are equipped with a back-upcamera and a monitor to assist the vehicle operator in moving thevehicle in reverse. However, such monitors can be a cause of excessivedistraction for the vehicle operator, depending on their location.

In addition, many monitoring systems are installed such that, due to theconfiguration of the parts, and the method of installation, should anintegral part like the monitor malfunction, accessing, fixing and/orreplacing the integral part is often cumbersome and expensive.

SUMMARY

Accordingly, a rear-view mirror and modular monitor system is providedthat includes an interior mirror that in some embodiments embeds amodular monitor behind, for example, see-through mirror glass. In someembodiments, the system includes multiple cameras, some in the vehicle,bus, school bus, public transit vehicle and/or truck, as well as somecameras outside the vehicle, bus, school bus, public transit vehicleand/or truck, advantageously providing the driver, other individualand/or other vehicle passenger an opportunity to view what is happening,for example, in the back rows of the bus and/or cabin, while also usingthe mirror to look at objects in the bus and/or cabin that are visibleusing the mirror.

Embodiments of the rear-view mirror and modular monitor system enablethe maximizing of safe usage by automating when the modular monitor willdisplay images, and when the driver will have full view of the rear-viewmirror. For example, one type of automation is time based, wherein acertain intervals images are displayed (e.g., during hours when it isknown that children will be on-board a bus). Another type of automationis event-based, wherein an image may be displayed when the door ofvehicle is opened, when red flashers are activated, and/or when the stoparm is activated. Images from a rear-view camera may be displayed insome embodiments only when the vehicle is placed in reverse. In someembodiments, two or more of the above automated viewing features may beused in combination.

In some embodiments the system comprises manual input selection, for usein certain situations. For example, when a driver cannot see activityhappening behind high seat backs or otherwise outside the view of thedriver, even with a rear-view mirror, a driver may choose to view suchactivity without having to stop the vehicle or adjust the rear-viewmirror.

In some embodiments, audio may be provided to the vehicle operator incoordination with video being displayed. For example, a driver may havea need to hear audio from an area inside or outside the vehicle.Embodiments of the system therefore provide microphones at or nearlocations where cameras are capturing images, and the audio can beprovided to the driver along with the images, by way of a speaker,headset, or the like.

A multi-camera, rear-view mirror and modular monitor system includes arear-view mirror that in some embodiments embeds a monitor behind, forexample, see-through mirror glass. In some embodiments, the rear-viewmirror and modular monitor system includes multiple cameras, some in thevehicle (e.g., a bus or truck, which are collectively referred to as a“bus”), as well as some cameras outside the bus, advantageouslyproviding the driver or other individual an opportunity to view what ishappening, for example, in the back rows of the bus and/or cabin, whilealso using the mirror to look at objects in the bus and/or cabin, and/orbehind the bus, that are visible using the mirror. In some embodiments,a standard 6×30 mirror is advantageously used in the bus to view, forexample, children that are behind the driver. In some embodiments, thisstandard 6×30 mirror is not needed for viewing traffic behind the bus,and in some embodiments it may be used to view objects other thanvehicles both inside and outside the bus. In some embodiments otherstandard and/or custom sized rear-view mirrors may also be used.

In some embodiments, a standard rear-view mirror is used in combinationwith the dual-vision camera inventions described in U.S. applicationSer. No. 12/608,600, filed Oct. 29, 2009, entitled “Method and SystemWith Multiple Camera Units Installed in Protective Enclosure,” whichclaims priority to U.S. Application Ser. Nos. 61/109,763, filed Oct. 30,2008 and 61/245,080, filed Sep. 23, 2009, and each of the aboveapplications are incorporated herein by reference in their entirety.

In addition or alternatively, in some embodiments, any other suitableimage capturing system is also contemplated for use either inconjunction with, or instead of, the dual-vision system. For example,any digital imaging device such as a digital camera and/or a digitalvideo recorder may be used.

Advantageously, multiple cameras are provided in, for example, a bus orother truck or vehicle as well as some cameras outside the bus,providing the driver an opportunity to see what is happening in areas inand/or around the bus that cannot be seen in the rear-view mirror, whilealso using the rear-view mirror to look at passengers and objects thatare visible through the mirror. In addition, in some embodiments, amonitor is either embedded behind see-through mirror glass, embedded ina cut-out aperture within the rear-view mirror, and/or otherwiseattached to a portion of the rear-view mirror. In any event, the drivercan view both the monitor and the rear-view mirror with relative easeand limited distraction to the driver.

In some embodiments, the interior cameras are located in the rear areaof the cabin of the bus and face forward in the bus to show the driverwhat is happening behind the high-backs of the seats which cannot beseen when looking up at a conventional mirror. Alternatively oradditionally, in some embodiments, cameras may be mounted in anysuitable location to capture images which would otherwise be unviewablefrom the rear-view mirror. This may include ceiling mounted cameras,side wall mounted cameras, rear facing cameras, and the like.

In some embodiments, external cameras may be located anywhere around theoutside of the bus that would provide views which can be helpful to thedriver. As an example, the present assignee describes an exterior camerasystem layout and driver controls which affords a view substantially360° around a school bus in U.S. patent application Ser. No. 13/177,302,entitled: “CAMERA SYSTEM FOR LARGE VEHICLES,” filed Jul. 6, 2011, whichis herein incorporated by reference in its entirety. The rear-viewmirror and modular monitor system can advantageously display at leastone selected imaging feed, and/or multiple imaging feeds simultaneouslyusing standard monitor technology and/or multiple monitor modulesconnected to the rear view mirror. Additionally, corresponding audio foran area inside or external to the bus being displayed on the modularmonitor may also be provided to the driver via the rear-view mirror andmodular monitor system, which, in some embodiments, incorporatesmicrophones built into the imaging devices and/or installed in thelocation of the imaging devices.

FIGS. 1a-1b depict a general layout of a system for effectuating thepresent invention in accordance with some embodiments of the invention.In some embodiments, rear-view mirror and modular monitoring system 100comprises, for example, at least three primary components: rear-viewmirror unit 110, modular monitor 120, and imaging device 130. Modularmonitor 120 and imaging device 130 are shown connected to each other viaconnection device 140.

In some embodiments, rear-view mirror unit 110 includes mirror 111 andat least one see-through mirror glass section 112, behind which modularmonitor 120 is mounted for display. In some embodiments, mirror 111 mayinclude a mirror cut-out aperture (not shown) in place of, or inaddition to, see-through mirror glass section 112, behind which modularmonitor 120 may be mounted for display. In yet other embodiments,modular monitor 120 may be mounted to any suitable portion of rear-viewmirror unit 110 that provides sufficient viewing of modular monitor 120and mirror 111.

In some embodiments, mirror 111 is a sheet of glass coated on the backside with black and chrome paint, making the front side reflective,similar to any standard rear-view mirror. As described herein, in someembodiments, a see-through mirror glass section may refer to a sectionof mirror 111 where the glass is coated with chrome paint only, orotherwise treated so as to make a standard see-through glass section 112sufficiently transparent (when viewed from the front) when a strongenough light source, such as the light from an activated monitordisplay, is channeled through the back of the section, and is otherwisereflective (when viewed from the front side) when the light source isnot provided or otherwise insufficient.

In some embodiments, the rear-view mirror has a unitary reflectingsurface of a single reflectivity or includes at least two areas ofdifferent reflectivity: a first area having a relatively lowreflectivity, and a second area, such as the remaining area of thereflecting surface, having a higher reflectivity. For example, asillustrated in FIG. 14a , the first area 1411 can be on one side of amirror 1410, and the second area 1412 can be the remaining area on themirror 1410. In alternative embodiments, the first area can be locatedin the other positions within the mirror 1400, for example, in themiddle of the mirror (1411′). As the first area is intended to cover anLCD monitor installed behind it, the placement and the size of the firstarea can be based on the size of the monitor screen and the monitorplacement. More than one area of low reflectivity can be included asdesired (e.g., if more than one monitor is used). The area of the higherreflectivity should be sufficiently large to ensure adequatereflectivity of the overall mirror. For example, the area of lowerreflectivity can be about ⅙ to about ⅓ of the whole mirror area.

Such embodiments address an important problem for the design of aninterior mirror which is intended to view the details of occupants of avehicle, e.g., a school bus, where the interior mirror is used mainly tosee details of, for example, students and/or children. As the interiorof the school bus usually only has limited lighting, we have determinedthat it is desirable that the mirror has sufficient reflectivity. (Bycontrast, a standard interior mirror of passenger cars does not need tobe as reflective because the mirror is used to see cars behind thevehicle which are visible either by their clearly defined daytime imageor by their headlights at night.) However, when the mirror is used inconjunction with an LCD monitor as described in one or more embodimentsof the present invention, the reflectivity should not be too high suchthat it would be difficult for the driver to see the images on the LCDmonitor because of the glare on the mirror caused by the light from thesurrounding environment (e.g., sunlight). In general, if the overallreflectivity of the mirror is, for example, in the 50-60% range, thewhole mirror will be bright but not transmissive; when the reflectivityis, for example, below 20% (such as glass without a reflective, tintedor other type of coating, which has a reflectance of, for example, about4% depending on the type of glass), the mirror is transmissive, and thusreflective images may appear too dark. A preferred reflectivity levelfor the mirror with single reflectivity (e.g., the reflectivity of themirror in zone 1412 is substantially the same as that in zones 1411 and1411′ and the zone being within 5% reflectivity of each other or thezones being similar to each other and within 10% reflectivity of eachother) would be between about 20% and 40%, alternatively between about25% and 35%, more preferably and/or alternatively still about 30% (e.g.,about a percentage reflects a 5% or less differential in reflectivityfor a specific reflectivity value), so the mirror is sufficiently brightfor a school bus with low interior lighting but transmissive enough tosee the images of the LCD behind the glass. A mirror having a uniformlow reflectivity is shown in FIG. 15a (when the monitor is off) and FIG.15b (when the monitor is on). Although the low reflectivity helps theLCD screen of the monitor shine through the mirror, we have determinedthat the images in the mirror can be too dark for the driver to see thedetails inside of the bus. Nonetheless, in some embodiments, anadditional tint may optionally be applied to either or both areas of themirror. This tint may be provided to reduce unwanted glare, such as fromsolar reflection, headlights or the like. In some embodiments, themirror may be tinted towards a specific color, such as yellow, byselectively preventing reflectance of unwanted wavelengths, such asblues and violets, so as to improve overall visibility. Tinting may alsobe provided to globally reduce the reflectance of all visiblewavelengths by a predetermined amount, such as from 5% to 50%.Combinations may also be provided, so as to both reduce the reflectanceof all wavelengths by a predetermined amount, such as 10% to 30%, whilefurther suppressing, or even eliminating, the reflectance of otherwavelengths, such as blues and violets. Any suitable optical filter orthin film may be used to provide such tinting.

In some embodiments with areas having different reflectivity, the higherreflectivity area can be made sufficiently high to ensure adequate lightis reflected from the mirror to allow clear view of the target viewingarea of the mirror, especially for low-light settings, such as theinterior of a bus later in the day, or the like. Meanwhile, thereflectivity of the lower reflectivity area can be selected such that ithas sufficient transmittance to allow the images on the monitor (whenthe monitor is on) to transmit through the mirror and overwhelm anyglare coming from the sunlight or other light from outside and/or insidethe bus so as to be viewable by the observer (e.g., a bus driver) undersuch lighting conditions. In this regard, in some embodiments. it ispreferable to use a monitor that has high LCD brightness.

In some embodiments, the monitor can have an LCD screen whose brightnesscan be manually adjusted, and/or automatically adjusted depending on theambient light and/or glare coming from other light sources. Asillustrated in FIG. 14b , in some embodiments, the monitor module 1430includes at least an LCD screen 1432, a control module 1435, and a lightsensor 1437. The light sensor (e.g., a photocell) can be mountedproximate the LCD screen and behind the first area of the mirror havinglow reflectivity, or mounted on the frame of the mirror, or otherlocations as preferred or desired. The light sensor 1437 can sense, forexample, the ambient light level and generate a corresponding electricsignal, and transmit the electric signal to the control module 1435,which can include a control circuit so that the signal received from thelight sensor 1437 can be processed to generate a control signal toautomatically adjust the brightness of the LCD screen 1432, such as bycontrolling the brightness of a backlight of the LCD screen 1432. Insome embodiments, different brightness settings may be used and/or userselectable to allow automatic brightness control responsive topredefined user and/or monitor settings. In alternative embodiments, inaddition to or instead of the automated control module 1435, a manualbrightness switch is used to control the monitor brightness.

With reference to FIG. 16. to manufacture the mirror having the twoareas of reflectivity, in some embodiments, the below exemplary process400 can be used: (step 402) applying one or more reflective coatings ofa first reflective material on the entirety of the mirror surface of amirror substrate; (step 404) masking the first area where the lowreflectivity is desired, and (step 406) applying a further coating ofeither the same reflective material, or a second, different reflectivematerial to the area outside of the masked first area. Alternativemethods can be used, for example, by applying a first reflective coatingonly on the first area and a second reflective coating only in theremaining area. Commonly known metal-based reflective materials and/orpaints can be used, for example, chrome-based coating or paint. Multiplelayers of coatings can be applied to the first area and/or the remainingmirror area as needed to obtain the desired reflectivity. In someembodiments, (step 408) the mask may be removed after one or more of thedesired reflective coatings have been applied, and in particular afterthe final reflective coating in step 406 has been applied. In someembodiments, an opaque coating, such as black paint, may be appliedbefore removal of the mask and thereafter the mask is optionally removedso that the first area is devoid of the opaque coating.

In some embodiments, the second area (having a higher reflectivity) canhave a reflectivity in the 50-60% range, while the first area ofrelatively low reflectivity can have a reflectivity of 25% to 35%, oralternatively of about 20% or lower. Embodiments with a 20% reflectivityarea are illustrated in FIG. 15c (when the monitor is turned off) andFIG. 15d (when the monitor is on). However, in such embodiments, becauseof the high contrast of reflectivity between the two areas, thedifference between the two areas can be visible when the monitor is off,as shown in FIG. 15c , (where the first area is visible as a darker areaembedded in a brighter area). This can cause discomfort or annoyance tothe driver. In preferred embodiments, the reflectivity of the first areaand the second area can be selected such that the difference inreflectivity between the first area and the other parts of the mirror isnot visible or perceivable under normal operating conditions (when themonitor is off), as shown in FIG. 15e (FIG. 15f shows such a mirror whenthe monitor is turned on). For example, the reflectivity of the firstarea 1411 can be selected to be about two-thirds of the reflectivity ofthe higher reflectivity area 1412 (e.g., the remaining mirror area),e.g., the reflectivity of the first area 1411 can be selected to beabout 30%, and the reflectivity of the second area 1412 can be selectedto be about 45%. High brightness LCD monitors can be particularly usefulin such embodiments to overcome the not-too-low reflectivity of thefirst area 1411, e.g., those have or can be adjusted to have abrightness of 1,000-1,2000 candelas per square meter. Other values ofreflectivity in the two areas (and/or the contrast ratio of thereflectivity between the two areas) can be selected based on differentapplications, parts of the country, positions of the mirror within thebus, etc. In yet other embodiments, the reflectivity of both the firstarea 1411 and the second area 1412 can be substantially the same orsimilar to each other, such as between 20% and 40%, between 25% and 35%,and/or around 25% or 30%. Masking may or may not be employed is suchembodiments. In some embodiments, second area 1412 may have an opaquebacking while first area 1411 does not.

In some embodiments, as shown in FIG. 14a , a transition region 1413 maybe disposed between the first area 1411 and the second area 1412, inwhich the transition region 1413 has an intermediate reflectivity thatis between the respective reflectivities of the first area 1411 and thesecond area 1412. In preferred embodiments, the transition region 1413has a plurality of successively increasing reflectivities from the firstarea 1411 to the second area 1412, so that the reflectivity of themirror 1410 steadily increases in stepwise fashion from the first area1411 to the second area 1412 within the transition region 1413. It willbe appreciated that, with a suitable number of steps and/or applicationof reflective material, the reflectivity of the transition region 1413can be made to appear to smoothly increase from a minimum value that issubstantially the same as the reflectivity of the first area 1411, andwhich abuts the first area 1411, to a maximum value that issubstantially the same as the reflectivity of the second area 1412 andwhich abuts the second area 1412. In one specific embodiment, the firstreflectivity of the first area 1411 and second reflectivity of thesecond area 1412 are substantially similar to each other (e.g., within5-10% of each other), and the reflectivity of the transition region 1413serves to provide a smooth or stepped blending between the first andsecond reflectivities.

In some embodiments, and referring back to FIGS. 1a and 1b , rear-viewmirror unit 110 includes mirror unit mounting brackets 113. Theconfiguration of mirror unit mounting brackets 113 is merely exemplary,and any suitable configuration which provides proper mounting supportfor rear-view mirror unit 110 in a vehicle is likewise contemplated.Additionally or alternatively, in some embodiments, rear-view mirrorunit 110 may be provided with a standard locking mechanism, as describedin further detail in the description of FIG. 7, to lock rear-view mirrorunit 110 in place.

In some embodiments, image capture device 130 is a standard digitalstill and/or video camera. In some embodiments, image capture device 130also includes Infrared (IR) Light Emitting Diode (LED) lighting (orequivalent IR lighting) for capturing images in low or no visibilitywithout requiring a flash or other bright light source. In someembodiments, a standard light source may be provided in addition to orin place of IR LED lighting. While image capture device 130 is shownhere with a wired connection to modular monitor 120, in some embodimentsimage capture device 130 may be a wireless device, which is controlledand transmits captured images wirelessly via a wireless transmissionsuch as Wi-Fi, Bluetooth, IR, cellular etc. Furthermore, while imagecapture device 130 is shown here as a stationary camera, in someembodiments image capture device 130 may be a standard motorized,multi-directional manually/automatically controlled camera, which mayprovide the operator with additional views inside and/or outside thebus. In some embodiments, image capture device 130 is powered by atleast one of the vehicle's internal power source, and a stand-alonepower source such as a rechargeable camera battery or a solar cell.

In some embodiments, connection device 140 comprises one or a pluralityof input feeds 141. In some embodiments, the input feeds 141 arestandard video input feeds, which can be connected to any number andcombination of devices. For example, input feeds 141 may be respectivelyconnected to multiple image capture devices 130 and/or a combination ofimage capture devices 130, audio capture devices (not shown), e.g., amicrophone, and/or other sensors, e.g., a photocell light sensor, asdesired. In some embodiments, connection device 140 further comprises apower feed 142 for providing power to modular monitor 120 from a powersource (not shown), e.g., the vehicle battery, and a line out feed 143,for connecting modular monitor 120 to an output device such as, forexample, a stand-alone speaker (not shown) or additional monitor (notshown).

In some embodiments, connection device 140 includes monitor video feed144, to provide at least one a digital image, an audio signal, sensordata, and power to the monitor 120, and to provide output from themodular monitor 120 to an output device. It will be readily understoodby those of ordinary skill in the art that, while in the embodimentsdescribed herein, connection device 140 is shown as one comprehensiveconfiguration, other embodiments providing for multiple separatestandard connection devices and/or other configurations employingstandard connection devices and/or wireless connections may also beused.

FIGS. 2a-2d depict several views of a rear-view mirror and modularmonitor assembly in accordance with some embodiments of the invention.In particular FIG. 2a depicts a front view of rear-view mirror unit 110and see-through mirror glass section 112, the exemplary location ofwhich is depicted by a hash-lined rectangle. It will again be readilyunderstood by those of ordinary skill in the art that, while in theembodiments described herein, see-through mirror glass section 112 isdepicted as being rectangular in shape, any other shape suitable forcommensurate with the shape of a monitor display to be attached theretois also contemplated. Additionally, as explained above, while thehash-lined rectangle is described as indicating the general location ofsee-through mirror glass section 112, in some embodiments, thehash-lined rectangle indicates the general location of a mirror cut-outaperture (not shown) in place of, or in addition to, see-through mirrorglass section 112, behind which modular monitor 120 may be mounted fordisplay. In yet other embodiments, modular monitor 120 may be mounted toany suitable portion of rear-view mirror unit 110 that providessufficient viewing of modular monitor 120 and mirror 111, withoutnecessitating see-through mirror glass section 112 or a mirror cut-outaperture. In yet other embodiments, the rear-view mirror may include anadditional section, slot or receptacle, optionally molded, within and/orintegrated with the housing to accommodate the monitor for connectionand facilitate easy removal therefrom.

FIG. 2b depicts a back view of the exemplary rear-view mirror unit 110of FIG. 2a , with modular monitor 120 fastened to the back, adjacent tothe reverse (back) side of the location of see-through mirror glasssection 112. It will again be readily understood by those of ordinaryskill in the art that, while in the embodiments described herein,see-through mirror glass section 112 and modular monitor 120 are shownlocated to one side of rear-view mirror unit 110, this is merelyexemplary, and other locations along mirror 111 are also contemplated.In addition to depicting mirror unit mounting brackets 113, FIG. 2b alsodepicts fixed mounting bracket 114, which is discussed in greater detailin the description of FIG. 7 below. Other embodiments include fewer ormore brackets, and other configurations as necessary to secure rear-viewmirror unit 110 in place. It should also be noted that, while theembodiments described herein depict rear-view mirror unit 110 as beingfastened to an internal portion of a vehicle, alternative embodimentswherein rear-view mirror unit 110 is mounting to an external portion ofa vehicle are also provided.

FIGS. 2c-2d depict several alternative views of rear-view mirror unit110 and modular monitor 120 in accordance with some embodiments.

FIG. 3 depicts an exploded view of a rear-view mirror and modularmonitor assembly in accordance with some embodiments of the invention.In particular, FIG. 3 shows how modular monitor 120 may be fastened torear-view mirror unit 110, and how rear-view mirror unit 110 may beassembled, in accordance with some embodiments of the invention.

In accordance with some embodiments, modular monitor 120 may be fastenedto rear-view mirror unit 110 with the use of self-clinching threaded pinfasteners, such as monitor fasteners 118, and monitor nuts 119 forsecuring monitor fasteners 118 in place. Other types of fasteners mayalternatively be used as well, such as screws, adhesives, snap fit,adhesive tape, velcro and the like. In some embodiments, modular monitor120 may be fastened directly to mirror unit backing 116 by threadingmonitor fasteners 118 through mirror unit backing apertures 165 locatedaround the perimeter of backing cut-out 172, and through modular monitorapertures 127, which are located along the perimeter of monitor frame126, and securing monitor fasteners 118 in place with monitor nuts 119.

However, in other embodiments, modular monitor 120 is fastened to mirrorunit backing 116 with monitor gasket 117 disposed therebetween. Monitorgasket 117 optionally includes gasket apertures 129. In someembodiments, monitor fasteners 118 are threaded first through mirrorunit backing apertures 165, then through gasket apertures 129, andfinally through modular monitor apertures 127, after which they aresecured with monitor nuts 119.

In some embodiments, monitor gasket 117 advantageously serves to blockexternal light from disturbing an image displayed on modular monitor 120by reaching monitor display 121 from between modular monitor 120 and thereverse side of see-through mirror glass section 112. Monitor gasket 117also serves to channel the light (image) emitted by monitor display 121through the reverse side of see-through mirror glass section 112, aswell as to protect monitor display 121 from any incidental rubbing orscratching against mirror unit backing 116. In some embodiments, monitorgasket 117 is configured and shaped to follow the perimeter of monitordisplay 121.

As shown in FIG. 3, in some embodiments, rear-view mirror unit 110 isfurther assembled by inserting mirror 111 into mirror unit backing 116and affixing mirror 111 in place using mirror frame 115. In someembodiments, mirror frame 115 is fastened to mirror unit backing 116 byway of additional fasteners. In other embodiments, mirror frame 115 isshaped and configured so as to become affixed to mirror unite backing116 when a sufficient force is applied to mirror frame 115, so that atleast a portion of mirror frame 115 is held in place over mirror unitbacking 116, such as, for example, by employing the use of a lip,indentation, or groove (not shown) to which mirror frame 115 can attach.Other methods of attachment are of course also contemplated, such by useof an adhesive or bond. Additionally, the back of mirror 111 and/or theinternal surface of backing 116, may be coated with a pressure-sensitiveadhesive or the like to better couple mirror 111 to backing 116. Incertain embodiments, the pressure sensitive tape or adhesive that isadded to the back of the mirror glass 111 is selected to make the glassshatter-proof or shatter-resistant.

In some embodiments, assembly of rear-view mirror unit 110 may becompleted by affixing fixed mounting bracket 114 to mirror unit backing116. In some embodiments, fixed mounting bracket 114 is connected toL-brackets 152 and 153 using fastener 166, washers 167, and nuts 168.L-brackets 152 and 153 are connected to mirror unit backing 116, forexample, by inserting fasteners 169 through L-bracket apertures 170 andaffixing them to backing bracket apertures 171.

While the above description of FIG. 3 provides an example embodiment ofan assembly of rear-view mirror unit 110 and modular monitor 120, thoseof ordinary skill in the art will readily recognize that many featuresof the above descriptions are exemplary in nature. For example, in placeof a fastener, an adhesive or bond might be employed.

FIGS. 4a-4e depict several views of a modular monitor in accordance withsome embodiments of the invention. FIG. 4a depicts a front view ofmodular monitor 120 in accordance with some embodiments. As can be seenin FIG. 4a , modular monitor 120 includes monitor display 121 on a frontface of the monitor. In some embodiments monitor display 121 is an LCDmonitor. However, other display types are also contemplated, such as LEDmonitors, OLED monitors, etc. In some embodiments, monitor display 121provides strong enough light levels so that images displayed on monitordisplay 121 will be clearly visible through see-through mirror glasssection 112. In alternative embodiments when a mirror cut-out apertureis used in place of see-through mirror glass section 112, a relativelyweaker display may be sufficient for proper visibility of the images.

FIG. 4b depicts a back view of modular monitor 120 in accordance withsome embodiments. As can be seen in FIG. 4b , modular monitor 120includes monitor speakers 122 on a rear face of the monitor. Of course,in other embodiments, monitor speakers 122 may be located on anotherside of modular monitor 120. In yet other embodiments, no speakers areintegrated into modular monitor 120, as can be seen, for example, inFIG. 2d . In some embodiments, an output port is provided in additionto, or in place of, monitor speakers 122, to provide audio output toexternal audio devices such as an external speaker, wired headsets,and/or wireless headsets.

In some embodiments, manual controls 123 are provided on modular monitor120. In some embodiments, manual controls 123 control power, volume,input selection, settings for automatic use, and/or other settings. Insome embodiments, modular monitor 120 includes sensor 124 and indicatorlight 125. In some embodiments, sensor 124 may be a photocell lightsensor, which detects levels of ambient light in the area around modularmonitor 120, and can adjust the brightness of monitor display 121 tocompensate for excess and/or insufficient light. Indicator light 125 maybe configured to indicate, for example, that modular monitor 120 ispowered on or off, and/or operating correctly.

In some embodiments, modular monitor 120 may have built-in and/orremovable memory (not shown) for recording images and/or audio.

FIGS. 4c-4e depict additional views of modular monitor 120 in accordancewith the invention.

FIGS. 5a-5d depict several views of an example image capture device 130in accordance with some embodiments of the invention. As explainedabove, in some embodiments, image capture device 130 may be for example,a standard digital still and/or video camera, an IR/LED camera or thelike. Additionally, in some embodiments, image capture device 130 mayfurther comprise a built-in audio capture device (microphone).Furthermore, though image capture device 130 is shown with a wiredconnection device, a partially or completely wireless image capturedevice is also contemplated. Likewise, in some embodiments, imagecapture device 130 may be powered by the vehicle, and/or may have aninternal battery.

FIGS. 6a-6d depict several views of a vehicle with a rear-view mirrorand modular monitor system installed in accordance with some embodimentsof the invention. In some embodiments, as illustrated in FIG. 6a seenfrom behind the driver, when the bus is in reverse, monitor display 121can be configured to always show camera 3 view (back-up) as shown inFIG. 6d . When not in reverse, the driver can then manually choose videoinputs from cameras 1, 2, or 3 (exemplary locations of which aredepicted in FIG. 6d ) from video input switch 180 by way of respectiveswitches 181, 182, 183, or choose no view at all (full mirror view).

In alternative embodiments, as illustrated in FIG. 6b seen from behindthe driver, when the vehicle is in reverse, monitor display 121 can beconfigured to always show camera 3 view (back-up). When not in reverse,the driver can use video input switch 180, located on dashboard 185, tochoose a single-feed configuration providing a video input from eithercamera 1 or camera 2, a multiple-feed configuration providing a splitvideo input of cameras 1 and 2, input from camera 3, or no view at all(full mirror view).

In additional alternative embodiments, the selection of the view for themonitors can be based on driver preference using a standard input switchmechanism, manually or manually activated. For example, when not inreverse mode, the driver might still want camera 3 providing input tothe monitor as part of the multiple-feed split video configuration.

FIG. 6c depicts a view from above of an exemplary location of rear-viewmirror unit 110 and video input switch 180 relative to the driver. FIG.6d provides exemplary mounting locations for cameras within and externalto the bus.

In some embodiments, the video switch 180 or other existing oradditional switch can be configured to select one or more video feedsfrom one or more cameras based upon one or more optional triggeringsignals. In some embodiments, a first triggering signal comprises abackup signal that indicates that the vehicle has been placed in reverseand/or is ready to move in reverse. Any suitable method may be used toobtain such a signal, such as by using the backup lights, a signal fromthe transmission, drive selector moved to reverse, or the like. A secondoptional triggering signal comprises a stop-completed signal, indicatingthat the vehicle has completed a stop and is preparing to move forwardin continuance of its journey. Any specific method may be used to obtainsuch a signal. With specific reference to busses, the stop completedsignal can be obtained, for example, from monitoring when the door hasbeen closed; that is, the closing of the passenger door can beinterpreted as a stop completed signal, which can be used by the videoswitch 180. In a school bus, for example, the stop completed signal canbe optionally obtained by monitoring the flashing lights that aredisplayed when a school bus has stopped and/or other shifting of the businto forward or reverse gear, and the like. In some embodiments, whenthe flashing lights cease flashing (e.g., are turned off) or the gearshave changed or moved from parked to forward or reverse, this event canbe interpreted as a stop completed signal.

In busses, and for school busses in particular, it is very desirable tohave an external view of one or more the sides of the bus as the vehiclepulls away from a stop, as individuals that are in close proximity to abus when the vehicle pulls away may be inadvertently struck by thevehicle. To provide a driver with ample opportunity to review the sidesof or around the bus for hazard conditions, in one embodiment the videoinput switch 180 is configured to monitor the stop completed signal andto selected a video feed from an external camera for display in monitordisplay 121 for a predetermined amount of time after receiving the stopcompleted signal, such as for 5 to 15 seconds, more preferably about 10seconds. In some embodiments, the selected video feed is from one ormore cameras that monitors a side(s), front or rear of the bus. Forexample, with reference to FIG. 6d , upon receiving the stop completedsignal, such as when the bus doors close and/or the flashing warninglights are turned off, the video switch 180 selects a video feed fromcamera 2 and causes this feed to be presented on display 121 for 10seconds; alternatively, a split-view scene could be presented in display121 formed by the video splitter 180 by a combination of the video feedsfrom both cameras 1 and 2 so that both the left and right sides of thebus are presented in a single view 121.

Although backup cameras are highly desirable when backing up a vehicle,in some situations their use may be discouraged in favor of side viewand/or rear view mirrors. Hence, in some embodiments, upon receiving thebackup signal, the video switch 180 may temporarily disable the videofeed for the backup camera 3 for a predetermined amount of time, such as30 seconds to two minutes, more preferably for about one minute, andinstead require the driver to use the external mirrors instead ofrelying on a monitor in the interior of the bus. After thispredetermined amount of time has elapsed the video, switch 180 may thencause the video feed from the backup camera 3 to be presented in thedisplay 121, assuming that the bus is still in reverse as indicated bythe backup signal or if such as display is manually requested, such asby a switch 183.

FIG. 7 depicts an optional lever lock mechanism which can be used tolock a rear-view mirror and modular monitor assembly in place inaccordance with some embodiments of the invention. In some embodiments,an optional lever lock mechanism can be used to lock rear-view mirrorunit 110 in place in the vehicle as currently offered by Rosco, Inc. ofJamaica, N.Y. and the assignee of the present application. According tosome embodiments, FIG. 7 depicts parts of the rear-view mirror unit'slocking mechanism 150, including the fixed mounting bracket 114 attachedto the vehicle and the shaft with a threaded end 151 that is passedthrough or positioned in L-brackets 152 and 153.

Shaft 151 is secured into place usinglock nut 157 on the outside of L-bracket 153 (on the side of theL-bracket 153 facing away from L-bracket 152). Also, lock washer 158 andlock washer 159 may be positioned on either side of tubular sleeve 156between L-bracket 152 and L-bracket 153. Shaft 151 is also passedthrough both sides of fixed mounting bracket 114. That is, one end offixed mounting bracket 114 may be positioned between tubular sleeve 156and L-bracket 152 and the other end of fixed mounting bracket 114 may bepositioned between the other end of tubular sleeve 156 and L-bracket153.

Handle 160 may be positioned on an end of shaft 151 and secured theretousing clevis pin 161 and spacer 162 and spacer 163 on either end ofclevis pin 161. Also, cotter pin 164 may be positioned on an end ofclevis pin 161 to secure it in place inside handle 160. It will beunderstood that, while particular components of locking mechanism 150are described herein, various parts may be omitted, or may be combinedand formed integrally, or the parts may be arranged in different wayswithout departing from the spirit of the present disclosure. Forexample, while helical compression spring 154 is described, it will beappreciated that other types of springs or non-spring urging members maybe used to apply pressure to L-bracket 152 as described below; or, whilemounting bracket 114 is described as being attached to the bus, othertypes of fasteners may be used to secure rear-view mirror unit 110 orlocking mechanism 150 to the vehicle.

FIGS. 8a-8b depict several views of a dual-vision camera system whichmay be used in conjunction with a rear-view mirror and modular monitorsystem in accordance with some embodiments of the invention.

In some embodiments, a dual-vision camera system can be used in placeof, or in conjunction with image capture device 130 to provide imagesand/or audio to modular monitor 120. The illustrative camera system,disclosed in incorporated by reference U.S. patent application Ser. No.12/608,600 cited above, records images of both the interior and exteriorof a vehicle. Specifically, the camera system provides for recording theinterior and exterior of a vehicle on a continuous loop, with the oldestdata erased by more recent video, and will save sequences of video andaudio recordings based upon certain predetermined recording events.

The dual-vision system 200 of FIGS. 8a and 8b includes in at least oneembodiment two cameras within the same housing: one camera capturesvideo of the interior of the vehicle, while the second camera capturesvideo of vehicles, pedestrians, road signs, traffic lights, etc. infront of the vehicle. In alternative embodiments, the dual-vision system200 is provided with a microphone to record audio within the interior ofthe vehicle. In alternative embodiments, different numbers of camerascan be used with different field of views, from a single camera to anumber of different cameras. One advantage of the camera system is thatit allows the recording of the video of the driver and/or passengers ofthe vehicle in addition to video of the outside of the vehicle to allowreview of events, such as distractions to the driver within the vehicle,car accidents, near-accidents, etc.

For example, according to one embodiment, the camera system recordsimages from both a camera pointed in the direction of travel of thevehicle as well as a camera pointed towards the interior of the vehicle.In some embodiments, the cameras capture images at regular intervals,for example, one frame every second or every other second, whereas inother embodiments, the cameras capture motion video at 15 frames persecond, 24 frames per second or 30 frames per second. In alternativeembodiments, the camera system stores video in a continuous loop on amemory or other standard data storage device, for example, a standard SDcard. As will be understood, other types of standard memory devices suchas hard drives, data storage, tape drives, etc. are contemplated by thecamera system. In alternative embodiments, the memory card, e.g., SDcard and the like, for the recording device is removable. The memorycard may be lockable to prevent theft or tampering with the data.

Video will continue to be captured, overwriting non-protected portionsof the memory until a recording event occurs such as the driveractivating a panic button, a g-force measured beyond a certain thresholdby an accelerometer in 3-axis, a g-force measured beyond a certainthreshold by an accelerometer in 2 axis, a sufficient bump is measuredby an accelerometer, excessive brake is measured by an accelerometer orother device connected to the vehicle braking system, speed exceeds acertain predetermined threshold, and the like. Audio and/or videocaptured in response to a recording event is stored for later review andwill not be overwritten by continuous loop recording until indicated byan individual with sufficient permissions, e.g., transportation manager.Captured video and/or audio recorded in response to a recording event,in alternative embodiments, is recorded on a separate part of the memorycard or alternatively a separate memory that cannot be over-writtenexcept by someone with additional permissions, e.g., transportationmanager. In some embodiments, video and/or audio captured before and/orafter the event is stored in a separate memory or protected area of thememory or marked as non-erasable to prevent its erasure. In someembodiments, the type of recording event, e.g., braking event,collision, etc., is stored along with the audio and/or video of therecording event to allow sorting of recordings at a later time.

In certain embodiments, the dual-vision system 200 is provided with abuilt-in standard GPS sensor, which can determine the location, speedand direction of the vehicle. In certain embodiments, the GPS locationof the vehicle is recorded along with the audio and/or video recorded ina continuous loop. In other embodiments, the GPS location is recordedonly when a recording event occurs. In alternative embodiments, the dualcamera system unit 200 can optionally connect directly to the windshieldor other location of the vehicle directly without the need of anadditional enclosure. For example, the slots/grooves on either the frontor back side can be used to connect/slide into any standard mountingunit for connection to the vehicle.

In alternative embodiments, an event counter is beneficially providedthat counts by each type of recording event in the aggregate and/orseparate counter for each type of event. The counter includes or isconnected to a display that displays either always or byrequest/actuation of a switch that optionally is only accessible to themanager for efficient determination whether the actual recording eventsshould be viewed by, e.g., the manager.

In alternative embodiments, an audible chime is included that makes anaudible sound and/or light indicator that illuminates if thevehicle/driver exceeds predetermined speed and/or for predeterminedrecording events such as excessive braking, and the like.

In alternative embodiments, a delay timer is included which allows thedevice to continue to capture video for a predetermined time after theignition is turned off. Alternatively, the system captures still framesat regular intervals (e.g. 15 or 30 sec) to see if anyone is in and/oraround the vehicle and/or captures video and/or still images when theignition is off and a motion detector is triggered to prevent theftand/or record events in the vicinity of the vehicle.

In alternative embodiments, when forward and backward cameras are used,either two separate cameras are provided on opposite sides of a mirror,such as a rearview mirror, one camera pointing forward and anotherpointing backward. In other embodiments, a single structure having twocameras integrated therein, one pointing forward and the second pointingbackward as described herein may be used.
